[ Upstream commit 751f524635a4f076117d714705eeddadaf6748ee ] Because after an object is dropped, requests for that object are useless, cancel them to avoid causing other problems. This prepares for the later addition of cancel_work_sync(). After the reopen requests is generated, cancel it to avoid cancel_work_sync() blocking by waiting for daemon to complete the reopen requests.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
